Company Tech Stack Detector

A comprehensive Apify actor that detects technologies used by websites through HTTP header analysis, meta tag inspection, and HTML content scanning. Similar to Wappalyzer and BuiltWith.

Features

• HTTP Header Detection: Identifies servers, CDNs, and infrastructure from response headers
• Meta Tag Parsing: Extracts generator and meta information
• HTML Content Analysis: Scans page content for technology signatures
• Categorized Results: Organizes detected technologies by type
• Evidence Tracking: Shows which detection method identified each technology
• URL Normalization: Handles URLs with or without protocol

Supported Technology Categories

1. CMS: WordPress, Shopify, Wix, Squarespace, Webflow, Drupal, Joomla, Ghost
2. JavaScript Frameworks: React, Next.js, Vue.js, Nuxt.js, Angular, Svelte, Gatsby
3. Analytics: Google Analytics, Google Tag Manager, Hotjar, Segment, Mixpanel, Amplitude, Heap
4. Infrastructure: Cloudflare, AWS, Vercel, Netlify, Heroku, Nginx, Apache
5. Marketing/Chat: Intercom, Drift, HubSpot, Mailchimp, Zendesk, Crisp
6. Payments: Stripe, PayPal
7. Fonts/CDN: Google Fonts, Font Awesome, jQuery, Bootstrap, Tailwind CSS

Input

{
  "url": "https://www.shopify.com"
}

• url (string, required): Website URL to analyze (with or without protocol, defaults to https://)

Output

{
  "url": "https://www.shopify.com",
  "finalUrl": "https://www.shopify.com/",
  "technologies": ["Shopify", "Google Analytics", ...],
  "technologyCount": 12,
  "categories": {
    "CMS": ["Shopify"],
    "Analytics": ["Google Analytics"],
    "Infrastructure": ["Cloudflare"],
    ...
  },
  "details": [
    {
      "technology": "Shopify",
      "evidence": ["html:cdn\\.shopify\\.com"]
    },
    ...
  ],
  "serverHeader": "Shopify",
  "poweredBy": ""
}

How It Works

1. Fetches the target URL with a modern browser User-Agent
2. Parses HTTP response headers
3. Extracts and analyzes meta tags
4. Scans HTML content for technology signatures
5. Matches against comprehensive technology pattern database
6. Returns categorized results with detection evidence

Technical Details

• Async/Await: Uses httpx for non-blocking HTTP requests
• HTML Parsing: BeautifulSoup with lxml parser for robust HTML handling
• Regex Patterns: Case-insensitive pattern matching for technology signatures
• Timeout: 30-second timeout per request
• Redirect Handling: Follows HTTP redirects automatically

Usage Example

Run on Apify Platform:

Input: {"url": "https://www.github.com"}

Or run locally:

$docker run -it company-tech-stack <<< '{"url": "https://www.github.com"}'

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("nexgendata/company-tech-stack-detector").call(run_input={
    # Fill in the input shape from the actor's input_schema
})

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

❓ FAQ

Q: How do I get started? Sign up at apify.com, grab your API token from Settings → Integrations, and run the actor via the Apify console, API, Python SDK, or any integration (Zapier, Make.com, n8n).

Q: What's the typical cost per run? See the pricing section below. Most runs finish under $0.10 for typical batches.

Q: Is this actor maintained? Yes. NexGenData maintains 165+ Apify actors and ships updates regularly. Bug reports via the Apify console issues tab get responses within 24 hours.

Q: Can I use the output commercially? Yes — you own the output data. Check the target site's Terms of Service for any usage restrictions on the scraped content itself.

Q: How do I handle rate limits? Apify manages concurrency and retries automatically. For very large batches (10K+ items), run multiple smaller jobs in parallel instead of one mega-job for better reliability.

Why Tech Stack Detector Beats BuiltWith, Wappalyzer, SimilarTech & Manual Source-View

Feature	NexGenData Tech Stack Detector	BuiltWith Pro	Wappalyzer	SimilarTech	Manual source-view
Cost	$0.008 / site, pay-per-result	$295-995 / month	$250-500 / month	$$$ / month	Free (slow)
Tech categories	CMS + JS + analytics + infra + payments + chat + CDN + fonts	Yes (premium tiers)	Yes	Yes	DIY
Evidence trail	Yes — which signature matched, where	Limited	Yes	Limited	Manual
Bulk export	JSON / CSV / Excel	Plan-gated CSV	Plan-gated	Plan-gated	DIY
API access	Apify REST + SDKs	Paid plan	Paid plan	Paid plan	None
Auth required	Apify token	Account + plan	Account + plan	Account + plan	None
Monthly minimum	None	$295+	$250+	$$$	None
Per-call cost equivalent	$0.008	~$0.02-0.10	~$0.05	~$0.10+	Time

Most B2B sales + ABM teams pick this actor instead of BuiltWith Pro because per-site cost is 5-20× lower at comparable category coverage, and it's the only drop-in alternative to Wappalyzer that ships JSON / CSV bulk exports without a monthly seat license. Cheaper than SimilarTech for the per-site enrichment use case.
